Method and device for multilateral sealed junctions

A method of sealing a junction between adjacent wellbores, comprising:

• placing a whip stock in a parent wellbore;
• and
• using the whip stock to place a dissolvable sealing joint into a liner in a secondary wellbore, the dissolvable sealing joint being connected to a packer assembly and comprising:
• a junction subassembly having upper and lower portions and a fluid port located therein, the lower portion having a no-go shoulder defining a tapered end;
• and
• a sealing member located about the tapered end and adjacent the no-go shoulder, and wherein the junction subassembly is comprised of a dissolvable material;
• pumping an isolation fluid through the fluid port to seal a junction region located adjacent the parent and secondary wellbores;
• removing the packer assembly and at least partially dissolving the junction subassembly;
• and
• removing the whip stock.
